Breathing, which is
primarily concerned
with maintaining life,
is secondarily a force
assisting in
vocalization. It
consists of two phases
--- inhalation and

5.
LUNGS
• Serve as the
reservoir of air
• As you inhale, fill
the lungs
comfortably in
preparation for
speaking.

6.
Diaphragm
• A large sheet of
muscle separating
the chest cavity
from the abdomen
• Forms the floor of
the chest and the
roof of the
abdomen
• Gives pressure to
the breath stream

7.
BREATHING EXERCISE:
• 1. Sit up straight. Exhale.
• 2. Inhale and, at the same time, relax the belly muscles. Feel as though the
belly is filling with air.
• 3. After filling the belly, keep inhaling. Fill up the middle of your chest. Feel
your chest and rib cage expand.
• 4. Hold the breath in for a moment, then begin to exhale as slowly as
possible.
• 5. As the air is slowly let out, relax your chest and rib cage. Begin to pull
your belly in to force out the remaining breath.
• 6. Close your eyes, and concentrate on your breathing.
• 7. Relax your face and mind.
• 8. Let everything go.
• 9. Practice about 5 minutes.

Phonation takes place when
voice is produced in speaking as
the expiratory air stream from
the lungs goes up through the
trachea or windpipe to the
larynx.

10.
Larynx
• Principal organ of
phonation
• Found at the top
of the trachea
• Protuberance is
known as the
“Adam’s apple”

11.
Vocal Cords
• A pair of bundles
of muscles and
cartilages
• Open and close
at various
degrees

12.
Trachea
• Also known as
windpipe
• Passageway of
air going up
from the lungs

13.
PHONATION EXERCISE
• Think about blowing out birthday
candles.
• Begin to blow and then turn the breath
into an "ooo" sound on a comfortable
pitch. Feel the tone begin in the
breathing muscles.
• Repeat

15.
The voice produced in
phonation is weak. It
becomes strong and rich
only when amplified and
modified by the human
resonators. Resonation is
the process of voice
amplification and
modification.

16.
Pharynx
• Common passageway
for air and food
• Located behind the
nose and mouth and
includes the cavity at
the back of the tongue
• Divisions of the
pharynx:
– Nasal pharynx
– Oral pharynx
– Laryngeal pharynx

17.
Nose
• Consists of the external and
internal portions
• Nostrils – openings of the
external nose
• Nasal cavity – internal nose;
directly behind the external
nose through which the air
passes on its way to the
pharynx
• Septum – divides the
external and internal nose
into two separate
passageways

18.
Mouth
• Divided into the vestibule
and the oral cavity
proper
• Vestibule – felt by placing
the tongue tip outside
the teeth but inside the
lips
• Oral cavity – felt by
retracting the tongue,
closing the jaws and
moving the tongue about
